Laser engraving on aluminum
Discover the fascinating world of laser engraving on aluminum and how to achieve impressive results.
Laser engraving on aluminum is a precise and demanding process, and different factors need to be borne in mind. The type of surface—whether unfinished, colored anodized, or clear anodized aluminum—can have a major impact on the result, so special attention is required to achieve the best possible markings.
Laser engraving on colored anodized aluminum
Colored anodized aluminum is ideal for engraving. The darker the aluminum is anodized, the better the contrast will be. The anodized layer is removed during the engraving process, allowing the bright, almost white glow of the aluminum below to shine through. Not only is this type of engraving rapid and cost-effective, it is also very popular for labeling or personalizing promotional gifts.Laser engraving on clear anodized aluminum
Clear anodized aluminum allows for a very dark, contrast-rich engraving, but this process takes significantly longer than engravings on colored anodized aluminum. This is because of the special technique used, which does not involve removing the surface layer. Instead, targeted heat is applied to change the color and make the engraving visible. This process requires more time and precision, but the result is impressive. Since this type of engraving does not remove any material, the insulating anodized layer is not damaged. One advantage of this is that it stops as much dirt from building up.
Engravings on unfinished aluminum
It is possible to engrave unfinished aluminum, but unfortunately, the resulting contrast is very low. Depending on the alloy, level of expertise, and suitable configurations, we can achieve a good color change.
Using special pigment sprays opens up new possibilities for engraving on unfinished aluminum. This innovative technique produces impressive contrasts and permits a wide range of applications.
Discover the benefits of this technique, most suitable for sheets, individual parts, and small-batch series. Engraving on unfinished aluminum with pigment spray is the most time-consuming type of engraving: The spray first has to be applied and then removed after engraving. Despite the complexity of the process, it is still possible to achieve impressive, visually appealing results.
